2D Low-Contrast Resolution Phantom
QRM-2DLC
provides the opportunity to evaluate
low contrast resolution in CT and FDCT and to optimize tube current,
collimation, pitch and image
reconstruction for the desired lowcontrast resolution in all types of
clinical applications.
The Phantom has been designed to evaluate the
imaging capabilities of 3D X-ray imaging
modalities in the x/y-plane. CT-scanners lowcontrast resolution capabilities can be obtained by
a single spiral scan using axial images and coronal
reformations. The phantom visualizes the impact of
all scan, image reconstruction, and display
parameters.
2DL with different contrast cylinders of
-10 HU and -20 HU!
Two series of different low-contrast cylinders with
diameter varying from 5 mm to 15 mm are located
in the 100 mm diameter cylindrical body of
homogeneous tissue-equivalent material.
